“…Additionally, fractal models were used for the first time to evaluate the porosity of the material resulting in a fractal dimension range of 2.5–3. The biological activity of the halloysite and halloysite/magnetite composite showed that both the halloysite and the composite were biocompatible, promoting the growth of E. coli M-17 bacteria in a nutrient medium and providing a protective environment for beneficial bifidobacteria to flourish …”

Halloysite nanotubes (HNTs) have emerged as one of the promising clay minerals that have myriad applications due to their unique properties. The presence of silica and alumina groups on the outer and inner surfaces allows surface modifications with different functional compounds. Depending on the applications required, numerous desired compounds have been used for both inner and outer surface modifications to construct hybrid noanostructures which further enhance their physiochemical properties. This review discusses the surface design with special emphasis on magnetic nanoparticles to fabricate HNT-based magnetic nanostructures which display synergistic effects and summarizes potential applications in the fields of catalysis, magnetically driven drug delivery, chemotherapy/diagnosis, environmental remediation, emulsification, and microwave absorption.

The bacterial anode in microbial fuel cells was modified by increasing the biofilm’s adhesion to the anode material using kaolin and graphite nanoparticles. The MFCs were inoculated with G. sulfurreducens, kaolin (12.5 g·L−1), and three different concentrations of graphite (0.25, 1.25, and 2.5 g·L−1). The modified anode with the graphite nanoparticles (1.25 g·L−1) showed the highest electroactivity and biofilm viability. A potential of 0.59, 0.45, and 0.23 V and a power density of 0.54 W·m−2, 0.3 W·m−2, and 0.2 W·m−2 were obtained by the MFCs based on kaolin–graphite nanoparticles, kaolin, and bare anodes, respectively. The kaolin–graphite anode exhibited the highest Coulombic efficiency (21%) compared with the kaolin (17%) and the bare (14%) anodes. Scanning electron microscopy and confocal laser scanning microscopy revealed a large amount of biofilm on the kaolin–graphite anode. We assume that the graphite nanoparticles increased the charge transfer between the bacteria that are in the biofilm and are far from the anode material. The addition of kaolin and graphite nanoparticles increased the attachment of several bacteria. Thus, for MFCs that are fed with wastewater, the modified anode should be prepared with a pure culture of G. sulfurreducens before adding wastewater that includes non-exoelectrogenic bacteria.
